Ore A has goethite[FeO(OH)] as the main phase and contains 0.06 wt pct sulfur. But Ore B has Fe 2 O 3 as the main phase and contains 0.03 wt pct of sulfur. In the sinter mix condition, ores A and B were mixed in the weight ratio of 8 to 2, which simulated the use of various iron ores mixed in the actual sintering process.

coke, limestone, return, as percentages against the total iron ores, or as proportion against the total iron ores, these being also in wet condition;-a part of the iron ores, before reaching the sintering plant, are passed through the raw materials preparation sector, where are mixed and homogenized, having as result the iron ore

SINTER PLANT Doc. No: RG / 05 Rev no.: 00 Effective Date: -- 1. OBJECTIVE Sintering is an agglomeration process of fine mineral particles into a porous mass by incipient fusion caused by heat produced by combustion within the mass itself. Iron ore fines, coke breeze, limestone and dolomite along with

FUNDAMENTALS OF IRON ORE SINTERING R. P. Bhagat INTRODUCTION The process of sinter making originated from a need to make use of fines generated in mines and in ore benefiCiation plants. With the development of sintering technology, a sintering plant has become a tremendous success for providing a phenomenal increase in

the ore to yield an upgraded product substantially low in alumina. To utilize the large amount of iron-ore fines produced during mechanized mining and in the ore-handling plants, the provision of sintering facilities has been proposed in almost all the steel plants. Generally the fines have higher alumina and silica contents than the lumpy ore.

Sintering Plant. Sinter is produced in Sintering Machines from Iron Ore fines, Coke fines and flux (Limestone & Dolomite) and other metallurgical wastes generated in the plant like Mill Scale, Flue dust etc. There are 3 Sintering Machines at the Sintering plant in Bokaro Steel Plant. Two machines have a hearth area of 252 m2 each and one of 276 m2.

Sinter plants 73 030301 Sinter plants Process description By sintering, the pelletisation of fine-grained, smeltable ores, iron ore in particular, to compact lumps by heating nearly to the melting or softening point is understood. Melting tendencies at the grain boundaries lead to a caking of the material.
